Filed: 1991-12-19
Abstract: PURPOSE:To select driving characteristics most suitable for respective wide- range uses by controlling the number of transistors TRs to be actually driven out of plural driving TRs connected in parallel to an output terminal. CONSTITUTION:When an external load connected to an output terminal T1 is heavy or quick switching is requested, a driving capability control register R1 is so set that buffers B12 and B13 are driven together with a buffer B11, and thereby, the performance requested to a buffer circuit is satisfied. Meanwhile, when the driving capability of the external load is not relatively requested but reduction of the power consumption is requested, the driving capability control register R1 is so set that buffers B12 and B13 are not driven, and thereby, the through current in buffers B12 and B13 is eliminated, and the power consumption in the buffer circuit is reduced to a required value. Consequently, driving characteristics most suitable for respective wide-range uses are selected.

Title: Semiconductor vapor-phase epitaxy apparatus
Inventor: TANAKA TOKUJI
IPC: H01L21/205
Filed: 1991-12-20
Abstract: PURPOSE:To prevent a breakage, which occurs sometimes in a conventional apparatus by dropping, etc., at the time of housing a substrate in a susceptor, by equipping the title apparatus with the susceptor arranged vertically in a reaction vessel, a substrate holder for retaining a semiconductor substrate and a substrate holder-inserting recess provided in the susceptor. CONSTITUTION:At the time housing a substrate 16 in a susceptor 1 in a barrel- type vapor-phase epitaxy apparatus, the substrate 16 is mounted by the use of e.g. vacuum pincette in a state where a jig 21 is inserted into a groove 5 attached to a part of substrate holder-housing groove 4 to remove a substrate holder 2 once from the susceptor 1 and to make the holder level. After that, the substrate holder 2 is caught again by the jig 21 and inserted into the susceptor 1 to house the substrate 16. Further, the jig 21 is equipped with three pawls 21a for catching the peripheral edge of the substrate holder 2. Because the substrate can be mounted when it is merely dropped into the recess of the substrate holder in the manner of matching the recess while it is held in the level position by one pincette, a dropping accident at the time of mounting the substrate can be prevented and workability is improved remarkably.

Filed: 1990-11-30
Abstract: PURPOSE:To prevent malfunction from occurring by providing a means which permits or prohibits the acception of dial data from a medium from which the dial data is generated, and permitting the acceptance of the dial data in a standby state. CONSTITUTION:When a call is issued from a call issuing part 3, it is connected to an opposite machine, and transmission is started. However, since no data of a card dialer received by a light receiving part 4 is required while the transmission is performed, an interface switch is turned off just before the transmission is started. Since the data of the card dialer is required in the standby state after the transmission is completed and before it is returned to the standby state, the interface switch is turned on, and the data from the card dialer is validated. The interface switch is turned off in the case other than the standby state, and the dial data from the card dialer 9 is neglected.
